Title: K&N Air Filters
Post by: BoisBlancBoy on May 20, 2008, 12:27:43 PM
With K&N air filters, like the one that comes with the MOD Quad kit, once it gets dirty cause you wash it out and re-oil it, or do you have to buy a new filter?

Do you have to use anything special to wash them with or will gas work just fine?

Soap and water works for me.  I don't like gas becuase it can deteriate the filter material.

Yeah I just found a the Recharge kit they sell.

Hey guys check this out and see what you think:

K&N Air Filters, CT recommends K&N air filters always be used in conjunction with an Outerwear or K&N pre-charger. K&N air filters are best for sand only. Unfortunately K&N's will pass fine dust particles, so we don't recommend them for desert racing or all conditions. K&N air filters have very good airflow characteristics and will keep out the big stuff just fine.

I found this at this site:     http://www.ctracing.com/air.htm

Just happened to stumble across it.  After reading that, kinda makes you wonder whats passing through your filter in any dusty conditions!

Good find, I run outwears, and haven't noticed any particles, but that don't mean there not getting through.

I always run an outerwear on my filter. Just peace of mind and its not doing any harm at all.

Yeah I have an outter wear on and after reading that I am for sure not going to take it off.  If I remember right, the package that the outer wear came in said to always have it on in dusty conditions.

I dont see why you woud take it off anyway. Your not losing any performance with it.

I run K&N with an outerwears and i ride all conditions, sometimes very dusty, and i never noticed a problem.

When you want to clean it just get the recharge kit, thats what i do, or if your tight on money u can just use soap and water.

k&n and outwears just go hand in hand

and use the k7n recharge kit, ive seen not so good results of people using "other" methods

I just use dishwashing liquid and air dry. Re-oil, wiat 20 minutes, touch up any white areas on the filter. Re-install.

I just cleaned out Tahoe's filter last Thursday.

As hard as you ride, I'm sure it wasn't K&N's fault. The 350 has a tendancy to get hot since it's not water cooled. That's one thing I wish Yamaha would change. Make all sportbikes liquid cooled.

that probly had a lot to do with it. the mechanic told us it was the K&N's fault. weird thing is we had just put a new clutch in and i burnt out the clutch in two rides and there was clutch particles all in my oil. could that have been it?

Clutch particles in the oil would be common since it's a wet multi-plate clutch, unless you had a serious melt down.

I personally quit using the K&N filters because they let in to much dirt, if you ride all day with one then take it off and just wipe your finger around the inside of the intake hole you will have a finger full of dirt, you can hold the K&N up to the light and see how big the air holes are, very bad for your carb, valves and rings, I always run the dual stage foam, I don't like haveing to replace valves and pistons to often. :)

I have a EHS lid on mine and run a prefilter also I have two filters to switch out. I have had no problems, but have seen people who have from lack of cleaning. If you are the type of person who does not like maintaining you stuff then K&N is not the way to go.

You are exactly right, keep it cleaned, well oiled and run it with an outerwear. You'll be straight, ive ran k&n from very dusty to very wet conditions and never had a problem.  just keep it cleaned and well oiled
